Question : How to use Acronis?

I have downloaded the trial version of Acronis True Image and have been using it for a couple of weeks.  I have set it to do incremental backups every four hours.  I now have over a hundred incrementals.  In a year I would have thousands.

How do I manage them?  Do I need to save them all?  Should I do a full backup periodically and delete all the old incrementals? (This seems like a lot of work for a product that is supposed to be so easy to work with.)

Answer : How to use Acronis?

I must admit that I simply read the description and sent link.
You will need a database because you need to store records of the long and short URL.
Technically it's not the only option short of writing each apache rule for each URL or using a text file but do not recommend anything else except for database because of ease, security and speed.

Here are 7 free scripts that look very promising.
